There is a new Beta test version of the Linkage software: https://www.rectorsquid.com/beta/linkage.msi

The only significant difference from the previous version is a fix to keep the color of drawing elements when copying and pasting. Drawing elements might have also lost their color when saving files but I didn’t test that. Since the “paste” code is the same as the “open file” code, I suspect there could have been a problem.
